WILLIAM G. UANFIELD, OF ST. LOUIS, IiIISSOUBI.

WINDOW! REFRIGERATOR.

Application filled April 18, 1922. Serial No. 554,621.

To all whom it may concern:

Be it known that I, WILLIAM G. CAN- FIELD, a citizen of the UnitedStates, residing at St. Louis, in the county of St. Louis City and Stateof Missouri, have invented new and useful Improvements in VVindOWRefrigerators, of which the following is a specification.

This invention relates to a window refrigerator, and the object is toprovide a cabinet or the like to be applied to the inner side of awindow sash, and so constructed that the outside temperature or nearlythat temperature will be maintained in the cabinet.

A further object is to provide a device of this type having one openside and insulated walls on the remaining sides with means for eflectingair tight contact with the surface of the glass in the window sash, sothat the air within the cabinet will be maintained at substantially thetemperature of the outer air and of the glass unaffected by thetemperature ofthe room in which the cabinet is located.

A still further object is to provide a cabinet of this character withparticular means for permitting access to the interior, and particularmounting means.

With the foregoing and other objects in view, the invention consists inthe novel construction and arrangement of elements described andclaimed, it being understood that modifications may be made within the 5scope of the claims without departing from the spirit of the invention.

In the drawings, Figure 1 shows the refrigerator in front elevation; thewindow sash and glass on which it is mounted being broken away; Figure 2is a horizontal section through the structure of Figure 1; Figure 3 is avertical section through the lower element of the sash, and a portion ofthe bottom of the refrigerator; Figure 4, is

4.5 a section through a combined ventilating and securing device; Figure5 is a fragmentary section showing modified mounting means.

The cabinet includes side walls, top and bottom walls, and a front wall,all of these elements being double and providing an interior air space,for insulation.

The outer side walls are designated 10 and 12, and the corresponding topand bottom walls are shown at 13 and 14-, the front wall of the outerstructure being designated 15.

The inner walls, spaced from said outer walls form the inner structureshown at The air chamber, afiording insulation is desto ignated 18, andextends between all side walls correspondingly located, and the variousother walls of the cabinet.

Gaskets 19 and 20 are located in grooves 21 and 22, in the edge portionsof the wall, these gaskets effecting air tight connection with the glassof the window sash.

Connecting and supporting rods 25 and 26 extend vertically through thecabinet walls, and lugs or nuts, such as at 27, are threaded onto therods, at the points shown and contacts with the adjacent elements of thecabinet.

Openings are provided in the front walls of the inner and outerreceptacles, and these openings are closed by doors 30 and 31, mountedon spring hinges 32 and connected by a link 33, so that both doors openat the same time. The door frames are designated 34: and 35.

Outside air may be admitted to the interior, when desired, by passing atube 5 through the window sash, or frame, and connecting this tube withthe entrance to a bore drilled through one or more of the rods, the boreopening within the cabinet.

The bottom of the box or cabinet rests on the lower element of the sash.Brackets 36 and 37 are secured to the frame of the sash and carrysprings 38 and 39, each bearing on one of the rods and holding thecabinet lIi positive contact with the surface of the g ass.

It is intended that the outer surface of the cabinet shall have anatural wood finish, 5 and that the inner wall of the cooling chambershall be enameled.

The inner receptacle with its lining 16 may be removed, if desired, bydetaching the air connections. Figure 4c shows an upper vent 26, and itshould be added that one or more of the air connections may open intochamber 18.

In the modified form of Figure 5, I have shown an angular resilientmetallic element 41, held in position by short rods or bolts 42 andsupporting the lower portion of the outer receptacle. One flange of thisangular member extends into the lower element of the sash in theposition shown, and between the glass 43 and the sash element- 44. Theparts are so formed and proportioned that the edges of the receptacle orreceptacles are in close contact with the surface of the glass.

Having thus described the invention, I claim:

1. In a device of the class described, a receptacle formed with innerand outer spaced walls providing an intermediate air chamber and aninner chamber having one open side, means for mounting the receptacle incontact with the glass of a window sash, the mounting means includingresilient devices and securing elements, one of which is tubular, forplacing the inner air chamber in communication with the outside air.

2. In a device of the class described, a

receptacle formed with inner and outer spaced Walls providing anintermediate air chamber and an inner chamber having one open side,means for resiliently mounting the receptacle in contact with the glassof a window sash, said mounting means including brackets mounted on thesash and springs connected with the brackets, rods passing through thewalls of the receptacle and threaded devices carried by the rods, thesprings engaging the end portions of said rods for retaining thereceptacle in po sition, one of said rods being tubular and admittingair to the receptacle.

In testimony whereof I afiix my signature.

WILLIAM G. CANFIELD.
